BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to data processing systems andin particular to search engines. Still more particularly, the presentinvention relates to a computer implemented method, apparatus, andcomputer usable program code for dynamic modification of advertisementsdisplayed in response to a search engine query.

2. Description of the Related Art

The Internet contains a large number of websites. When a user wants tolocate a website containing specific content, but the user does not knowwhich website to visit, the user typically uses a search engine. Asearch engine is a software program which indexes websites based on thecontent of each website and provides an interface in which the user canuse to search the index and find websites with specific content. Forexample, a user may enter one or more keywords, and the search enginewill return a list of all websites having content containing thespecified keywords.

When a user performs a query using an Internet search engine, the searchengine generates revenue for the owner of the search engine bydisplaying advertisements next to the results of the search enginequery. The results of a search engine query are based on the keywordsused in the search. Similarly, the advertisements which are displayednext to the search engine results are also based on the keywords used inthe search.

When a user enters a keyword which has more than one meaning, the searchengine returns search results which display websites having contentrelated to each different meaning of the keyword. The search engine alsodisplays advertisements corresponding to each different meaning of thekeyword. Currently, when a keyword in a search engine query has morethan one meaning, the advertisements displayed in response to the searchengine query are not tailored to the meaning of the keyword whichinterests the user.

SUMMARY OF THE INVENTION

The illustrative embodiments described herein provide a computerimplemented method, apparatus, and computer usable program code formodifying advertisements. A set of keywords is received from a user. Aquery is performed in a search engine with the set of keywords. A set ofwebsites comprising ranked search results and ranked advertisements isdisplayed. Responsive to detecting a user input selecting a firstwebsite in the set of websites, modifying the ranked advertisements,based on the content of the first website, to form modifiedadvertisements.

It shouldbe appreciated that FIGS. 1-2 are only exemplary and are not intended toassert or imply any limitation with regard to the environments in whichdifferent embodiments may be implemented. Many modifications to thedepicted environments may be made.

With reference now to the figures, FIG. 1 depicts a pictorialrepresentation of a network of data processing systems in whichillustrative embodiments may be implemented. Network data processingsystem 100 is a network of computers in which embodiments may beimplemented. Network data processing system 100 contains network 102,which is the medium used to provide communications links between variousdevices and computers connected together within network data processingsystem 100. Network 102 may include connections, such as wire, wirelesscommunication links, or fiber optic cables.

In the depicted example, server 104 and server 106 connect to network102 along with storage unit 108. In addition, clients 110, 112, and 114connect to network 102. These clients 110, 112, and 114 may be, forexample, personal computers or network computers. In the depictedexample, server 104 provides data, such as boot files, operating systemimages, and applications to clients 110, 112, and 114. Clients 110, 112,and 114 are clients to server 104 in this example. Network dataprocessing system 100 may include additional servers, clients, and otherdevices not shown.

In the depicted example, network data processing system 100 is theInternet with network 102 representing a worldwide collection ofnetworks and gateways that use the Transmission ControlProtocol/Internet Protocol (TCP/IP) suite of protocols to communicatewith one another. At the heart of the Internet is a backbone ofhigh-speed data communication lines between major nodes or hostcomputers, consisting of thousands of commercial, governmental,educational and other computer systems that route data and messages. Ofcourse, network data processing system 100 also may be implemented as anumber of different types of networks, such as for example, an intranet,a local area network (LAN), or a wide area network (WAN). FIG. 1 isintended as an example, and not as an architectural limitation fordifferent embodiments.

With reference now to FIG. 2, a block diagram of a data processingsystem is shown in which illustrative embodiments may be implemented.Data processing system 200 is an example of a computer, such as server104 or client 110 in FIG. 1, in which computer usable code orinstructions implementing the processes may be located for theillustrative embodiments.

The depicted examples in FIGS. 1-2 andabove-described examples are not meant to imply architecturallimitations. For example, data processing system 200 also may be atablet computer, laptop computer, or telephone device in addition totaking the form of a PDA.

The Internet contains a large number of websites. When a user wants tolocate a website containing specific content, the user typically uses anInternet search engine on a computer, such as client 110 of FIG. 1. Asearch engine is a software program which indexes websites based on thecontent of each website and provides an interface in which the user canuse to search the index and find websites with specific content. Thesearch engine is typically located on a server, such as server 104 ofFIG. 1. For example, a user may enter a set of keywords, where the setof keywords is one or more keywords, and the search engine will return alist of all websites with content related to the set of keywords.

When a user performs a query using an Internet search engine, the searchengine generates revenue for the owner of the search engine bydisplaying advertisements next to the results of the search enginequery. The results of a search engine query are based on the keywordsused in the search. Similarly, the advertisements which are displayednext to the search engine results are also based on the keywords used inthe search.

When a user performs a query of a search engine using one or morekeywords, the search engine returns results from the search andadvertisements. The results and advertisements are each ranked by thesearch engine. The ranked search results are results ordered by thesearch engine based on certain criteria. Similarly, the rankedadvertisements are advertisements ordered by the search engine based oncertain criteria. The criteria for ranking the search results and thecriteria for ranking the advertisements are typically, but notnecessarily, different.

The rank of each result or advertisement determines the order in whichthe results and advertisements are displayed in the browser. The higherthe rank of a result or advertisement, the higher the result oradvertisement is placed when displayed in the browser. Similarly, thelower the rank of a result or advertisement, the lower the result oradvertisement is displayed in the browser.

The results obtained by the search engine are links to websitescontaining content that the search engine considers relevant to thekeywords the user entered. Thus, a website is ranked higher if thesearch engine considers the website to be more relevant to the keywords.The search engine ranks the websites in the results based on therelevance of the content of the websites to the keywords. The relevanceof the results to the keywords is determined by the search engine usingvarious criteria.

For example, the search engine may weigh different criteria, such as thenumber of times the keywords occur on the website, the popularity of thewebsite, and how many other websites link to the website in determiningthe relevance of the website to the keywords. Therefore, a search resultwebsite is ranked higher or lower depending on whether the search engineconsiders the content of the website more relevant or less relevant,respectively, to the keywords.

The search engine also ranks the advertisements which are displayed nextto the results of the search. The advertisements are links to websitescontaining products or services related to the keywords. The advertisertypically pays the search engine provider to display the advertisementsnext to the search results. For example, the advertiser may pay thesearch engine a flat fee to display the website whenever certainkeywords are entered into the search engine, or the advertiser may paythe search engine only if the user actually visits the website of theadvertiser.

In determining the ranking of an advertisement, the search engine maytake into account different criteria, such as how many times thekeywords occur on the website of the advertiser, and how much money theadvertiser is paying the search engine. For example, if the websites oftwo advertisers are equally relevant in other respects, the advertiserpaying more money may be ranked higher than the advertiser paying lessmoney.

Once the search engine has ranked the results and the advertisements,the links to the websites of the ranked results and the links to thewebsites of the ranked advertisements are sent to the browser anddisplayed to the user.

For example, assume a user wants to search for websites containinginformation about restaurants serving East Indian food in Dallas, Tex.The user may enter the keywords “Indian restaurant Dallas” in the searchengine and submit a query looking for websites containing all threekeywords. In response to the user query, the search engine will displaya list of websites containing all three of the specified keywords, andthe search engine may also display advertisements for restaurantsserving Indian food in Dallas.

When a user enters a keyword in a search engine to find informationabout a particular topic, and the keyword has more than one meaning, thesearch engine may return search results containing several groups ofwebsites. Each group of websites may contain content related to eachdifferent meaning of the keyword. The search engine may also displaygroups of advertisements with each group of advertisements correspondingto each different meaning of the keyword.

When a keyword in a search engine query has more than one meaning, theadvertisements would be more relevant to the user if the advertisementswere tailored to the particular topic the user was searchingfor.—Therefore, the illustrative embodiments described herein provide acomputer implemented method, apparatus, and computer usable program codefor modifying the type of advertisements in response to a search enginequery.

The illustrative embodiments described herein provide a computerimplemented method, apparatus, and computer usable program code formodifying advertisements. A set of keywords is received from a user. Aquery is performed in a search engine with the set of keywords. A set ofwebsites comprising ranked search results and ranked advertisements isdisplayed. Responsive to detecting a user input selecting a firstwebsite in the set of websites, modifying the ranked advertisements,based on the content of the first website, to form modifiedadvertisements.

FIG. 3 is a block diagram of software components used to dynamicallyselect advertisements in accordance with an illustrative embodiment. Insoftware components 300, search engine 302 is software running on server304. Server 304 is connected to Internet 306. Client 308 is alsoconnected to Internet 306. Browser 310 is software running on client308.

User 312 interacts with browser 310. For example, user 312 may usebrowser 310 to navigate to the website of search engine 302. Searchengine 302 is a website for searching the contents of the internet, suchas Google™, Yahoo®, or MSN Search®.

User 312 types in keywords into browser 310 so that search engine 302can find and display websites with content related to the keywords. Forexample, assume user 312 navigates to the website of search engine 302and then types keywords into browser 310. Browser 310 sends keywords 313to client 308, and client 308 sends keywords 314 across Internet 306.Internet 306 delivers keywords 316 to server 304. Server 304 sendskeywords 318 to search engine 302.

Search engine 302 receives keywords 318 and searches the index on server304 for websites containing information about the keyword. Search engine302 also determines which advertisements the search engine shouldprovide for the user. The search engine ranks the results and ranks theadvertisements using various criteria.

Search engine 302 sends the results of the search, results andadvertisements 320, to server 304. Server 304 sends results andadvertisements 322 to Internet 306. Internet 306 sends results andadvertisements 324 to client 308, and client 308 sends results andadvertisements 326 to browser 310.

Browser 310 then displays the search results and the advertisements touser 312 using the rankings which the search engine determined for theresults and the advertisements. Search engine 302 can further modify theranking of the advertisements based on the websites which user 312visits after the initial search results and advertisements aredisplayed.

FIG. 4 depicts a browser window in accordance with an illustrativeembodiment. In browser window 400, browser 402 is an Internet browser,in which a user has gone to search engine 404 and performed a searchengine query using keyword 406. Browser 402 may be a browser, such asbrowser 310 in FIG. 3, and search engine 404 may be a search engine,such as search engine 302 in FIG. 3.

In this example, only one keyword, keyword 406, is shown. However, thoseversed in the art will appreciate that keyword searches may containmultiple keywords and Boolean operators specifying how the search shouldbe performed and that the techniques disclosed for use with one keywordmay be applied to multiple keyword searches.

In this example, keyword 406 has three different and distinct meaningswhich keyword 406 is commonly used to convey. The three meanings in thisexample are purely for illustration purposes. Those versed in the artwill appreciate that the embodiments may be used for any set of keywordswith more than one meaning.

In this example, keyword 406 has three meanings. One meaning is mostrelevant to the user while the other two meanings are less relevant.Relevant means that the user is particularly interested in one meaningof keyword 406 and is not as interested in the other two meanings ofkeyword 406. A first meaning of keyword 406 is more relevant than asecond or third meaning when the first meaning is what the user intendedwhen initiating the keyword search using the search engine.

In response to the query, search engine 404 initially returns three setsof results, results 408, 410, and 412. Initial results 408, 410 and 412are ranked by the search engine based on the relevancy of results 408,410, and 412 to keyword 406. The set of websites most relevant tokeyword 406 are ranked the highest and displayed on top, in result 408,and the least relevant set of websites are ranked lower and displayed onthe bottom, in result 412.

Result 408 represents a first set of websites related to the firstcommon meaning of keyword 406, where a set is a list of one or morewebsites. Result 410 represents a second set of websites related to thesecond common meaning of keyword 406. Result 412 represents a third setof websites related to the third common meaning of keyword 406.

In response to the query, search engine 404 also displays three sets ofadvertisements, advertisement 414, 416 and 418, based on the ranking ofthe advertisements by the search engine. Advertisement 414 represents afirst set of advertising ranked highest because the advertising isrelated to the first common meaning of keyword 406. Advertisement 416 isranked lower because advertisement 416 is related to the second commonmeaning of keyword 406. Advertisement 418 is ranked lowest becauseadvertisement 418 is related to the third common meaning of keyword 406.Advertisements 414, 416, and 418 are ranked by the search engine in theorder of relevance to keyword 406 based on the initial query. The set ofadvertisements ranked most relevant to keyword 406 are displayed on top,in advertisements 414, and the least relevant set of websites aredisplayed on the bottom, in advertisements 418.

An advertisement, such as advertisement 414, 416, or 418, is usuallyseveral lines of text designed to catch the interest of the reader, anda hyperlink to a website, where the advertiser has more information onthe advertiser's products or services. The advertisement may alsocontain a picture or other graphic image.

The user may only be interested in the third meaning of keyword 406 butis initially shown advertisements related to all three meanings ofkeyword 406. The user views results 408, 410 and 412 and determines thatresult 412 is related to the third meaning of keyword 406 and thereforeof interest to the user. The third meaning of keyword 406 is, in thisexample, most relevant to the user.

After submitting a query to the search engine using keyword 406, theuser may visit a website in results 408, 410, and 412 or a website inadvertisements 414, 416, or 418. The user typically visits the websiteswhich contain content related to the meaning of the keyword which ismore relevant to the user.

For example, after the user determines that result 412 is the meaning ofkeyword 406 which the user is interested in, the user may click onwebsites belonging to the set of websites in result 412, or the user mayclick on a website in advertisement 418 because the website is relevantto the meaning of keyword 406 which the user is interested in. Based onthe websites which the user visits after the initial search results aredisplayed, the search engine can determine which meaning or meanings ofkeyword 406 are most relevant to the user.

Typically, after a user visits a website in results 408, 410, and 412 oradvertisements 414, 416, or 418, the user clicks on the “back” button ofbrowser 402 to return to the search engine results shown in browser 402so that the user can visit additional websites from the results or theadvertisements. When the user returns to the search engine results page,the search engine may modify the ranking of the advertisements displayedbased on the website which the user visited. The search engine can inferthat the user is interested in the meaning of keyword 406 which isrelated to the content of the website which the user visited.

For example, assume the user is interested in the third meaning ofkeyword 406. After the initial search, the user visits a website in theset of websites belonging to result 412. When the user returns to thesearch page, the search engine modifies advertisements 414, 416, and 418based on the content of the website which the user visited.

The modified advertisements may be the original advertisements butdisplayed in a different order, or the modified advertisements may havesome of the original advertisements removed and new, more relevant,advertisements added. The modifications to the displayed advertisementsare made based on which advertisements the search engine ranks higherand based on the websites the user visits after the initial searchengine query.

In this example, the search engine determines that the third meaning ofkeyword 406 is relevant to the user based on websites which the userclicked on after the initial search results were displayed. When theuser returns to the search engine results page, the search enginemodifies the order in which the advertisements are displayed and ranksadvertisement 418 higher so that advertisement 418 is displayed at thetop, followed by advertisement 414, and advertisement 416.

In addition, advertisement 414 or advertisement 416 may contain websitesdifferent than the websites displayed after the initial search. Thedifferent websites may be chosen based on the websites the user hasvisited after the initial search. Each time the user visits a websiteafter the initial search results are displayed, the advertisementsdisplayed on the search results page are modified. In this manner, theadvertisements displayed may be fine-tuned to the interests of the usersbased on the websites which the user visits after the initial search.

The advertisements which are displayed in response to an Internet searchengine query are dynamically modified based on the websites which theuser visits. The websites which the user visits may belong to results408, 410, and 412, advertisements 414, 416, and 418 or both the resultsand the advertisements. Each website which the user visits after theresults of the search and the advertisements are displayed is used tofurther modify the displayed advertisements.

Thus, the displayed advertisements are dynamically modified each timethe user returns to the webpage displaying the search results. Based onthe website the user visited, a determination is made whether thecurrently displayed advertisements are relevant to the user, and theadvertisements are modified and displayed as modified advertisements.New advertisements may be added to the displayed advertisements.Previously displayed advertisements may be removed from the displayedadvertisements. The displayed advertisements may be re-ranked based onthe relevance of the advertisements to the website the user visited.

In contrast, in a conventional system, the advertisements are notmodified based on the websites which the user visits after the searchresults and advertisements are displayed. In a conventional system, theadvertisements remain static and are displayed based on the initiallydetermined relevance to the keywords. The advertisements continue to bedisplayed as the user visits different websites, even if theadvertisements displayed are irrelevant to the user.

FIG. 5 is a flowchart of a process for a search engine in accordancewith an illustrative embodiment. The process in FIG. 5 is executed bysoftware on a computer or server. For example, software, such as searchengine 302 in FIG. 3, may perform the steps in the process.

The process begins when a set of keywords is received from a user (step502). The set of keywords is one or more keywords. The search engine hasan index for each website on the Internet, based on the content of eachwebsite. The set of keywords are used to search the index for websiteswith content related to the set of keywords (step 504).

The search results are ranked based on different criteria, including therelevance of the search results to the set of keywords (step 506). Theadvertisements are ranked based on different criteria, including therelevance of the search results to the user (step 508). The rankedsearch results and the ranked advertisements are sent to the browser ofthe user who typed in the keywords (step 510). The browser displays thesearch results and the advertisements.

The browser determines which website the user visits in the relevantsearch results or the relevant advertisements and sends a message. Thesearch engine receives the information about which website the user hasvisited (step 512).

The advertisements are modified based on the website which the uservisited to make the advertisements more relevant to the meaning of thekeywords the user intended (step 514). The advertisements are modifiedby any combination of (1) adding new advertisements, (2) removingadvertisements, or (3) re-ranking the advertisements which are displayedto change the order in which the advertisements are displayed.

If the order in which the advertisements are displayed is changed, thehighest ranked advertisement, based on the relevance of theadvertisement to the website the user visited, is displayed first.Similarly, if a new advertisement is added, the new advertisement isadded based on the relevance of the new advertisement to the website theuser visited. An advertisement which was initially displayed may beremoved based on the relevance to the website the user visited.

The search results and the modified advertisements are sent by thesearch engine to the browser (step 516). A determination is made whetherthe user has completed the search (step 518). If the answer is “no” andthe user has not finished with the search results, then the searchengine receives more information on which websites the user visited(step 512) and the process repeats. If the answer is “yes” and theprocess has finished, then the process ends.

The different illustrative embodiments described herein provide acomputer implemented method, apparatus, and computer usable program codefor modifying advertisements in response to a search engine query. Theillustrative embodiments described herein provide a computer implementedmethod, apparatus, and computer usable program code for modifyingadvertisements. A set of keywords is received from a user. A query isperformed in a search engine with the set of keywords. A set of websitescomprising ranked search results and ranked advertisements is displayed.Responsive to detecting a user input selecting a first website in theset of websites, modifying the ranked advertisements, based on thecontent of the first website, to form modified advertisements.

Advertisements and search results are initially displayed as a result ofa search engine query. The user may visit a website in the searchresults or a website in the advertisements. The advertisements aredynamically modified each time the user visits a website and returns tothe search results webpage. The dynamically modified advertisementsresult in advertisements which are relevant to the websites the user hasvisited after the initial search.

Because the dynamically modified advertisements are relevant to thewebsites which the user recently visited, the advertisements are morerelevant to the user. Because the advertisements are more relevant tothe user, the user is more likely to click on the advertisement andvisit the website associated with the advertisement. Each time a uservisits a website associated with an advertisement, more revenue isgenerated for the owner of the search engine.

Thus, dynamically modifying advertisements results in more revenue forthe owner of the search engine. The user is also more satisfied with thesearch engine because the advertisements displayed more closely reflectthe interests of the user.
